First find the mass of the snack
Next find the temperature of a measured amount of water.
Now set the snack on fire.
Hold the burning crisp under the boiling tube of water.
This should raise the temperature of the water.
Sometimes the crisp needs relighting
Then try with the next snack
Take the temperature of the water at the end
Then complete the calculations to work out the energy
Maths meet science! But which crisp had the most energy?
